LABELING- Application filed August 20,

To all whom it may concern Be it known that I, JAMES Q. LEAVITT, a citizen of the United States, and a resident of Ogden, in the county of Weber and State of Utah, have invented a new and Improved Labeling-Machine, of which the following is a full, clear, and exact description.

This invention relates to improvements in labeling machines, an object of the invention being to provide improved means for applying labels to the ends of cans.

A further object is to provide improved means for feeding the cans onto a track and provide improved means for moving the track vertically so that the cans receivefirst a daub of paste, then a label and then a smoothing or pressure brush to firmly apply the labels to the cans.

A further object is to provide improved mechanism for controlling themovement of the cans, the application of the paste, the application of the label, and the smoothing or pressing operation, all of said mechanisms operating in unison and simultaneously, the several operations taking place at different stations.

A further object is to provide a machine of the character stated embodying novel details and combinations of parts, all of which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view in front elevation illustrating my improved machine, showing the can track elevated and the cans in position for-receiving the paste label and smoothing and pressure brush.

Fig. 11 is a bottom view of the label contamer shown in Fig. 10.

A represents a stationary openWork frame which constitutes the main support of my A motor 1 preferably machine or, of course, the machine may be driven from any desired source of power.

The motor 1 is supportedat the base of frame and the drive pulley 2 of the motor is connected by a belt 3 with a large pulley 4 on a' transversely ositioned shaft. 5 supported in the frame A pinion 6 on shaft 5 transmits motion to a gear wheel 7 on the main shaft 8 of the machine This shaft 8 1S positioned transversely of the frame A and operates to drive all of. the movable parts of the machine.

A vertically movable track B is sup orted and,

as shown most clearly in Fig. 9, consists of a pair of'an'gle iron'rails 9, 9, having side frames 10 secured thereto, and said rails and side frames supported on transverse bars 11 having slots 12 therein forthe reception of screws or bolts 13 with clamping nuts it below to secure the rails and frames at any desired distance apart to facilitate the adjustmentof the track to accommodate cans C of any diameter.

The end bars 11 of the track B are secured to and supported on the upper ends of vertical rods 15, the'latter guided in perforated brackets 16 on'frame A and having collars 17 secured thereon. These collars 17 are engaged by the bifurcated outer ends 18 of levers 19, the said bifurcated portions 18 straddling the rods 15 below the collars 17.

The levers 19 are pivtally supported near their outer ends as shown at 20, and at their inner ends are perforated for the reception of lugs 21 on the outer ends of links 22. Coiled springs23 are located around the lugs 21 and against the levers 19 and nuts 24- are positioned on the upper ends of thelugs and permit of a certain amount of adjustment to give thev necessary cushion compensating connection between the parts.

The lower ends of the links 22am pivotally connected to an arm 25 which is pivotally supported by the frame A as shown at 26, and a cam 27 on the main drive shaft 8 engages the upper face of this arm or lever 25 and imparts downward movement to the same. hen the lever 25 is moved clownwardly, the outer ends of the lovers 19 are forced upwardly through the medium of the links 22 connecting the levers 25 and 19, and said movement of the levers 19, through the medium of the rods 15, operates to elevate the track B and the can C thereon.

A conveyer belt D is located at one side of and at the entrance end of the machine and is supported on pulleys 28 and 29 on shafts 30 and 31 respectively. The shaft 30 is connected by beveled gears 32 with a vertical shaft 33 and the latter is connected by beveled gears 34 with a horizontal shaft 85, said shaft 35 being connected by beveled gears 36 with the main drive shaft 8 so that motion is imparted through the said shafts and gears to operate the conveyer D.

It is, of course, to be understood that each of said shafts will have suitable mounting; in the frame A and the beveled gears will be fixed to the shafts so that motion will be transmitted from the main shaft 8 to the conveyor D.

This conveyer D is located at the entrance end of the machine and extends across the entrance end of track B and receives the cans in a vertical position from a twist chute 87 to which the cans are supplied in any approved manner. Ordinarily the cans are fed in horizonal position, and hence, a twist, such as shown at 37, is necessary to bring the cans to an upright or vertical position and deposit them on the conveyer D, and guide frames 38 are provided at the sides of the conveyor to prevent lateral displacement of the cans during their movement on the conveyor.

It will be noted particularly by reference to Fig. 2 that the cans C on the conveyer D are moving at a right angle to the cans C on the track B. The movement of the cans on the conveyor D is limited by an extension 39 on one of the side frames 10 of the track which extends across and above the conveyer D and stops the cans against further movement on the conveyor.

The cans are fed step-by-step along the track B by forcing a can from the conveyer D onto the track at each step-by-step operation. This operation is performed by means of an angle arm 40 which is adjustably secured to a longitudinally movable rod 41 by means of a bracket This rod 41 is movable at one end in a guide bearing 48 and at its other end is bifurcated and provided with a pair of rollers 44 between which the upper end of a lever 45 is positioned. 'The lower end of this lever 45 is fulcrumedon a rod 46 mounted in the frame A anda coiled spring 47 connects the lever 45 with the frame A and holds the latter in normal position.

A cam 48 on the main shaft 8 is adapted to engage the lever 45 and force it to the direction to force the can C from the conveyer D onto the track B and during this movement push the whole line of cans on the track a distance of one can and eject a can at the discharge end of the track into a suitable guide or chute 49, from which the cans are conveyed or moved to any desired point of discharge.

It will be noted that the angle arm 40 has a relatively long member 50 which operates to hold back the cans on the conveyor D and permit, or rather compel but a single can to move from the conveyer D onto the track B at each operation of the arm.

'Above the track B and in position to be engaged by the cans G when the latter are elevated, I provide a dauber E, a label receptacle F and a rotary brush Gr spaced apart the proper distance so as to exactly center with the cans and be engaged in turn by the cans as they are moved step-by-step from one station toanother.

The danber E is carried by a bar 51 movable transversely across the upper'portion of the frame A and preferably between rollers 52 carried by bracket arms 53 on the frame. The dauber E may be adjustable vertically and I have indicated a simple form of adjustable means consisting of a screw threaded handle 54 on the dauber having adjusting nuts above and below the bar 51. A pin on the bar 51 is adapted to engage the rollers 52 and limit the forward movement of the dauber.

The forward portion of the bar 51 is movable between a pair of uprights 57 secured to brackets 58 on frame A. and is pivotally connected as shown at 59, to a relatively long bowed lever 60. This lever 60 is fulcrumed in frame A as shown at (31, and is engaged by a cam 62 on the shaft to move the lever 60 in one direction, and a coiled spring 63 connects the lever 60 with an arm on bracket 58 to move the latter in the opposite direction.

65 represents a paste cup or receptacle having a paste roller 66 therein adapted to be engaged by the dauber E and supply paste to the dauber when the latter is moved. to its rearward position as indicated in Fig 8. The paste roller 66 is secured upon a shaft 78 which is continuously revolved. This shaft 78 is connected by beveled pinions 79 to avertical shaft 80 and the latter connected by beveled pinions 81 with the main shaft 8 so that motion is continuously imparted to the paste roller.

At each step-by-step operation of the machine the dauber E is caused to move rearwardly by the spring 63 when permitted by the cam 62 so that the dauber moves from a position above the cams C to a position over and in contact with the paste roller 66 to receive a supply of paste therefrom, and as the cam 62 revolves, it will engage the lever 60 and force the dauber E back to normal position above the cans and in position to contact with a can when the track is elevated so as to supply a daub of paste to the end of the can. This daubing operation constitutes the first station of operation of the machine.

After the can has received this daub of paste, it is moved under the label supply receptacle, and when the can moves upwardly, it will contact with the lowest label 67 and when withdrawn, will carry the label on the can because of the adhesive which has already been applied to the end of the can.

The labels 67 are supported in a pile or column in the container F and are fed downwardly by means of a follower 68 and as the particular construction of this label feeding device forms thesubject matter of a sepa rate application, it will not be described in detail in this application except to say that the labels are fed downwardly and the lowermost label is removed by reason of the contact with the adhesively daubed can coming in contact therewith.

The rotary brush G is supported in a rotary sleeve 69 having mounting in a bracket '70 on an upright frame 71, and the brush G is vertically adjustable in the sleeve in any desired manner and I have illustrated a simple form of jam screw 72 for the purpose. A pulley 7 3 is fixed to the sleeve 69 and is con nected by an endless belt 74 'with a pulley 7 5 on the vertical shaft 33 so that rotary motion is supplied continuously to the brush G and the latter operates to press on and smooth the label so that it is firmly and smoothly affixed to the can.

As it is desirable to adjust the machine for the accommodation of cans of different sizes, it is necessary to provide a mounting whereby the container F and rotary brush G can be adjusted longitudinally of the ma chine. A simple means of adjustment is to provide slots 7 6 in theframe 71 and secure the supports for the brush and the container to the frame by means of bolts 7 7 projected,

through these slots.

The arm 40 above referred to is adjustable relative to its supporting bracket 42 to exactly position said arm in accordance with the diameter of the cans and as above described, the track B is adjustable to receive cans of different sizes, hence, I am enabled with my machine to paste labels on the ends of cans of any ordinary size by merely adj usting the parts to suit.

The operation is as follows: The cans C are fed onto the eonveyer D and are moved thereby until coming into contact with the extension 39 of one of the side frames 10 of track B. The conveyer D is continuously driven through. the medium of the main roller 66.

shaft S,'beveled gears 36, horizontal shaft 35, beveled gears 34:, vertical shaft 33, beveled gears 32, and shaft 30 on which one of the conveyer pulleys 28 is fixed.

One can at a time is moved from the conveyer D onto the track 13 by means of the angle arm 40, and the movement of this angle arm 40 is caused by the engagement of the cam 48 with the lever 4&5, the latter moving the rod 41 longitudinally and with it the arm 40 to move a single can onto the track and force the line of cans longitudinally of the track to eject a can from the discharge end thereof, and during this operation the extension 50 serves to hold back the cans on the conveyer D.

After each step-by-step movement of the cans, the track B is caused to elevate, and this operation is as follows: The cam 2'? on main shaft 8 engages lever 25 and forces the latter downwardly and, through the medium of the links 22 and levers 19, the rods 15 are moved upwardly, thus bringing the cans in contact with the dauber E, container F, and rotary brush G. Thus the cans in turn receive a daub of paste from dauber E, then a label from the container F and are then brought in contact with the rotary brush G- to smooth and press the label into engagement with the can.

During the movement of the track B downwardly and before it is again returned to its upright position, the dauber E is caused to move transversely of the machine and receive a supply of paste from the paste This movement of the dauber E is first caused by the spring 63, the cam 62 permitting such operation, so that the spring 63 will move the dauber E to a position over and in contact with the paste roller 66. As the cam 62 revolves, it will engage the lever 60 and force the dauber E back to a position over a can ready for the next elevation of the track.

It will thus be noted that the dauber E, container F, and rotary brush G have stationary stations and with the can are moved vertically by the track so that the labels can be applied at each operation, but in succession, to the cans as they are fed longitudinally of the track.

Various slight changes might be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise detailsset forth, but consider myself at liberty to make surh changes and alterations as fairly fall within thespirit and scope of the appended claims.
